Description

Methyltris(2-Phenylethoxy)Silane is a specialized organosilicon compound featuring a central silicon atom bonded to a methyl group and three 2-phenylethoxy substituents. This unique structure makes it a valuable reactive intermediate and coupling agent, particularly in the synthesis of advanced silicone polymers and surface modification applications. It is essential for manufacturers in the silicone elastomer, adhesive, and specialty coatings industries seeking to enhance material properties like adhesion, thermal stability, and compatibility.

Application

• As a key monomer or crosslinking agent in the synthesis of high-performance phenyl-containing silicone resins and elastomers.
• As an adhesion promoter in silicone-based sealants, adhesives, and coatings for challenging substrates.
• As a surface modification agent to impart hydrophobic or specific functional properties to inorganic fillers like silica.
• As an intermediate in organic synthesis and pharmaceutical chemistry for introducing silane functionality.
• In the formulation of release coatings and mold-making materials where thermal and chemical resistance are required.
• For research and development of novel hybrid organic-inorganic materials (ORMOSILs).

Quality Control

Our Methyltris(2-Phenylethoxy)Silane is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a cool, dry place. Recommended storage temperature is 2-25°C. Allow the container to reach room temperature before opening to minimize moisture ingress.
